Directions

In a medium bowl, combine flour, sugar, baking powder, baking soda, cinnamon, and salt. In a large bowl, combine eggs, sour cream, and sweet potato. Gradually add flour mixture, stirring to combine. Turn dough out onto a heavily floured surface. Knead in flour with hands as needed (dough will be sticky). Roll out dough to 1/2-inch thickness. Cut out dough with a 2 1/4-inch round cutter. Cut out center of doughnuts with a 3/4-inch round cutter. Re-roll dough as needed.

In a Dutch oven, heat vegetable oil over medium heat to 360 degrees F. Cook doughnuts, in batches, in hot oil, 2 minutes per side, or until lightly browned. Drain on paper towels. Ice top of doughnuts with Maple Icing, and sprinkle with chopped pecans.
